BRUSH.

SPECIFICATION forming part of Letters Patent No. 791,510, dated June 6, 1905.

, Application filed December 12,1902. Serial No. 134,904.

To all whom it may concern.-

Be it known that I, ANsON L. SONN, a citi-' zen of the United States of America, and a resident of the city of Troy, county of Rensselaer, and State of New York, (havinga postoffice address at Lansingburg station, Troy, New York,) have invented certain new and useful Improvements in Brushes, of which the following is a specification.

My invention relates to improvements in brushes. I f

The object of my invention is to provide a brush in which the bristle tufts are at one of their ends secured within a cement or a composition, which cement or composition is when warm and plastic entered within a recess formed in the brush-back.

I attain this object by means of the mechanism illustrated in the accompanying drawings, in which Figure 1 is a perspective view of a brush Fig. 2 is a plan of a brush-back before the cement or composition is placed therein. Fig. 3 is a section along the line X X on Fig. 2.

Similar letters refer to similar part-s throughout the several views.

For the purpose of retaining the bristles of a brush in position a composition or cement has heretofore been used with bristles extending into the cement and the cement placed in a brush-back.

My invention is to provide a new and more effectual means for retaining the cement in the brush-back and at the same time make the completed brush lighter in weight than has heretofore been accomplished, so far as I am aware, in cement or composition brushes. The cement or composition is heavier than the wood,which is the material of which the brushback is usually constructed. Therefore it is desirable to have as little'composition as is consistent with good construction.

the bristles at the center, protruding farther from the brush-back than atthe edges, the raised portion B will not interfere with the proper contour of the ends of the bristles when cemented into the brush-back. As the cement or composition K is placed within the groove C in a softened and heated condition,

after remaining therein a very short time the cement or compositlon w1ll harden, and being pressed tightly within the groove the cement or composition clings to the edges and bottom of the groove and the top portion of raised portion B and holds the bristles firmly and positively in position.

What I.claim as my invention, and desire to secure by Letters Patent, is

In a brush the combination ofa composition; bristles secured to said compositioh; a brush-back provided with a raised center portion; a groove between said center portion and a ridge along the rim of the brush-back; said composition secured within said groove, substantially as described.

Signed by me at Lansingburg, Troy, New York, this 3d day of December, 1902.
